Nearsightedness and farsightedness are common vision problems caused by abnormalities in the cornea or eyeball. Nearsighted people struggle to see things in the distance, while farsighted people struggle to see things up close. Both can be corrected with glasses or contact lenses. Regular eye exams are recommended to slow vision deterioration.
Nearsighted and farsighted vision, or nearsightedness and farsightedness, are thought to be two of the most common vision problems in the world. Nearsighted people are usually able to see things up close, but often have trouble seeing things in the distance. Forward-thinking people typically have the opposite problem. Things up close appear indistinguishable, while things in the distance can be seen clearly. Myopic and farsighted vision is typically caused by abnormalities in the curve of the cornea or by an abnormal lengthening or shortening of the eyeball itself. Both conditions can usually be corrected with glasses or contact lenses.
Nearsightedness, the vision problem often referred to as nearsightedness or myopia, typically occurs when the curve of the cornea is too pronounced or when the eyeball itself is elongated in shape. These physical abnormalities mean that light can take longer than it should to reach the retina of the eye. Light from farther away objects can take so long to reach a nearsighted person’s retina, so objects in the distance can appear blurry. Myopia can be more or less serious, depending on the extent of the structural anomaly of the eye. Ophthalmologists can usually correct nearsightedness with eyeglasses, permanent or disposable contact lenses, or LASIK eye surgery.
Farsightedness, the vision problem often commonly called farsightedness or farsightedness, generally occurs when the curve of the cornea is too pronounced or the eyeball itself is abnormally compressed in length. These eye structure abnormalities mean that light rays can reach the retina of the eye sooner than they should. Light rays reflecting off nearby objects can reach the retina too soon, so that closer objects appear out of focus while objects further away appear clearly in focus. Again, hyperopia can be more or less serious, depending on the extent of the structural anomalies of the eye. Ophthalmologists can usually correct this condition the same way they can correct myopia, with eyeglasses, contact lenses, implantable contact lenses, or LASIK surgery.
Short-sighted vision, while common and easily corrected, can often get gradually worse over time. People suffering from both nearsighted and farsighted vision problems are generally advised to have regular eye exams and wear corrective lenses to help slow the deterioration of vision.
